Abstract:
For Mr. Azad, the solution was to think small: like a billionth of a meter small - nanoscale. If the iron oxide could be converted into nanoscale particles, the surface area available for a chemical reaction would increase many thousands of times.

It's the difference between the surface area of a sugar cube and the surface area of thousands of sugar grains.

But in Mr. Azad's world view, sugar grains are enormous boulders.

The industry publication, Nanotech Briefs, named Mr. Azad and his arsenic-hungry particles a Nano50 Award recipient - 50 promising technologies in the nanotech industry. The research will be featured in the publication's November issue.
